    <h1>A demo of the Chrome-only dotted or dashed background grid</h1>
    
    <p>
        This uses the newer addition to canvas from the canvas v5 specification - native dotted and dashed lines.
        As browsers add support you will be able to use the option in those too but initially it's only supported in Chrome.
    </p>
    
    <pre class="code">
obj.Set('background.grid.dashed', true);
obj.Set('background.grid.dotted', true);

    This goes in the documents header:
    <pre class="code">
&lt;script src="RGraph.common.core.js"&gt;&lt;/script&gt;
&lt;script src="RGraph.hbar.js"&gt;&lt;/script&gt;
</pre>
    
    Put this where you want the chart to show up:
    <pre class="code">
&lt;canvas id="cvs1" width="600" height="250"&gt;[No canvas support]&lt;/canvas&gt;
&lt;canvas id="cvs2" width="600" height="250"&gt;[No canvas support]&lt;/canvas&gt;
</pre>

    This is the code that generates the chart:
    <pre class="code">
&lt;script&gt;
    window.onload = function ()
    {
        var hbar = new RGraph.HBar({
            id: 'cvs1',
            data: [4,5,3,8,4,9,6,5,3],
            options: {
                labels: ['Mal', 'Barry', 'Gary', 'Neil', 'Kim', 'Pete', 'Lou', 'Fred', 'Jobe'],
                title: 'A dashed background grid',
                backgroundGridDashed: true,
                backgroundGridAutofitNumhlines: 9,
                gutterTop: 35
            }
        }).draw()

        var hbar2 = new RGraph.HBar({
            id: 'cvs2',
            data: [4,5,3,8,4,9,6,5,3],
            options: {
                labels: ['Mal', 'Barry', 'Gary', 'Neil', 'Kim', 'Pete', 'Lou', 'Fred', 'Jobe'],
                title: 'A dotted background grid',
                backgroundGridDotted: true,
                backgroundGridAutofitNumhlines: 9,
                gutterTop: 35
            }
        }).draw();
    };
&lt;/script&gt;
</pre>
